Setup a MS Windows type L2TP connection as per the docs on docs.astaro.com.
Then feed your vpn capable user name to the os x internet connect vpn l2tp wizard, and the user's password ... and the server address ... and the shared passkey you set up on the astaro box.
Granted I got this to work absolutely once, and only from inside my network. whenever try to connect via L2TP from an external ip address to my astaro box's public ip (WAN), it just sits there and times out. Any pointers would be super.
